Abstract: Worksite knowledge obtained in the manufacture of prefabricate concrete buildings have indicated that, the enough compression of fresh concrete in the mold depends on the tip and place of the external vibrators employed for vibration. The stability of the tip and position of the vibrators with the technic of trial and error bring about missing time and doesn?t give good output. Thus, the computer-aided mold design is necessary. In this work, the features of vibration of a mold employed in the generation of Kambeton Company were examined experimentally to install a basis for the computer-aided mold plan. For this goal, the field experiments of prefabricate concrete members have been carried out under vibration with the use of a dynamic strain meter. Time-dependent transverse deflection measurements were recorded at some measuring points on the surface of the mold of this member, for both empty and full of fresh concrete conditions. This paper is mainly concerned with the comparison of the experimental results of the steel mould under vibration by external vibrators. As shown from the test results in Figures, displacement values in empty mold vary quietly from the full mold. The test results show that the fresh concrete-mould interaction has to be considering in the mold plan.
